The BOSS ME-50B puts world-class bass effects in a rugged floor unit with simple pedal-style control. Effects on the ME-50B are divided into six sections - Compressor/Limiter, Master, Filter/Tone, Drive/Synth, Delay/Modulation and Expression Pedal-giving bassists a range of one-of-a-kind and rocking BOSS tones including new effects like Sound Hold, Octave Up and Kick Drum. From there, ME-50B effects can be edited using 23 knobs and controlled via three built-in footswitches and an assignable expression pedal. The ME-50B from BOSS is the piece no bass player should be without!

Overview

Featuring three footswitches with sections such as synth, filter and delay, a built-in volume/wah pedal and COSM amp modeling technology plus compressor/limiter, the Boss ME-50B Bass Multi-Effect is built with virtually every effect a bassist could want in one package. Capable of summoning the sounds of Boss favorites such as the Slow Gear and Defretter while serving up live staples with ease, the ME-50B is a great place to look for anyone interested in doing away with their pedalboard.

Pretty good multi-effects unit

This is the first multi-effect pedal I've liked. The older ones (e.g. zoom B2.1u) are too slow to react quickly enough when the effect is engaged. The ME-50B does not have this problem. My likes are very similar to the review from Jay W. PROS: section.

CONS: Only 3 control knobs per effect is limiting. For example - Start…

This is a good sounding unit with many useful features. Good all around effects. It's great for gigging as it saves me from taking my stupily large pedaboard.
Two major gripes..
1. The reverb is in the delay block, so no delay and reverb together which sucks.
2. No Line Out/D.I. Out... kind blows…

Finally!

Finally bumped into gear that works for the digitally-impaired yet gives more quantity and quality for price than many, many stomp boxes!
Been around a few years I guess. But it finally caught up with me. Finally!
